To me it looked like Oscar had no problem with ANYONE until he got to 147. I remember him having an incredible left hook, jab and speed. I also remember Jesse James Leija saying he didn't think a human could hit that hard. I think De La Hoya would Ko Mayweather inside 8.
Makes sense, as does sweat pea. ODH was a complete one handed fighter at 130-135. 140 has a slight edge to oscar with his power and he had some speed. But Floyd at 140, though he didnt fight the best. Looked like a monster. I mean he looked stronger and faster to me. 130 we all know floyd was a complete beast. I agree with Pea and Asterion. Floyd is the better fighter then ODH in my book all around. He is more complete.
I want to say DLH easily, but he's always faded in the late rounds. Still, he would win more early rounds and take the fight, even though the probably would struggle in the later rounds, as usual.
I don't think using the "post-prime DLH lost by a few points to prime PBF, so prime-DLH would beat prime-PBF" argument is valid. At this point in his career or at that weight class, Floyd just does enough to win. The more his opponent pushes himself to win, the more Floyd will push himself to beat him. Prime for prime I think Floyd would beat him at 130, 135, 140, and 147. At 130 and 135 it wouldn't even be close.
